Database Name: LWPI - The WPIDS/WPINDEX Learning File Description: LWPI is a training file intended for learning how to use the WPIDS/WPINDEX files. World Patents Index (Derwent Subscriber file: WPIDS; Non-subscriber file: WPINDEX) provides information on patent publications from the 31 most important industrialized countries of the world, from the European Patent Office and from the World Intellectual Property Organization. In addition, patent-related information from Research Disclosure and International Technology Disclosure is included. Each record in the database describes a patent family, starting with the new invention (Basic Patent) and adding information about the same invention issued in other countries (Equivalents). The records contain bibliographic data, Derwent-assigned titles, abstracts, general indexing and in-depth chemical and electrical indexing. Access to the chemical and electrical indexing is subject to subscription with the producer. Language of the database is English. Data from the World Patents Index database are also available in the printed publications Chemical Patent Index (CPI), Electrical Patents Index (EPI), General and Mechanical Patents Index (GMPI), WPI Gazette Service, and World Patents Abstracts (WPA). Subjects Covered: All patent-relevant areas of science and technology. Start of coverage varies by subject matter. Pharmaceuticals: 1963-; Agricultural chemicals: 1965-; Plastics and polymers: 1966-; All other areas of chemistry: 1970-; Mechanical, electrical and general technology: 1974- Source: Patent documents are covered from: Argentina: 1975 only; Australia: 1963-69, 1983-; Austria: 1975-; Belgium; Brazil: 1976-; Canada; China: 1987-; Czechoslovakia: 1975-; Denmark: 1974-; European Pat.

The hydrophilic component is selected from propylene glycol, liq. polyethylene glycols (PEG) and glycerol. The silicone polymer is the prod. of a Pt or Rh catalysed hydrosilylation reaction of a polysiloxane having alkylhydrogen siloxane units with a polysiloxane having unsatd. gps. The modulating component is either (I) an organic substance with two or more OH gps. per molecule or (II) a hydrophilic polymer which swells in aq. medium. ADVANTAGE - Simple and easily controlled mfr. methods can be used to give required properties, density, size. High release rates at zeo order may be achieved in the gut and release caused to occur in selected regions of the body. @(22pp Dwg.No.0/0) FS CPI GMPI MC CPI: A06-A00E3; A12-V01; B03-L; B04-B02C3; B04-C03D; B12-A01; B12-A06; B12-A07; B12-C08; B12-C10; B12-D01; B12-D04; B12-D06; B12-D07; B12-E06; B12-E08; B12-F01A; B12-F01C; B12-F05A; B12-G01B3; B12-G03; B12-H02; B12-K02; B12-K04; B12-M10A DISPLAY FAM (SET PATENT DERWENT) PI EP-100382 A 840215 (8408)* EN 19 pp R: DE FR GB EP-100382 B 861120 (8647) EN R: DE FR GB DE3274330 G 870108 (8702) US4696916 A 870929 (8741) ADT EP-100382 A 82EP-0304067 820802; US4696916 A 82US-0404743 820803 PRAI 82EP-0304067 820802 DISPLAY BRIEF AN 84-044156 [08] LWPI DNC C84-018462 TI Intravenous nutrient comprising fatty acid ester of carbohydrate - useful for stability with high calorie value and low osmotic action. DC B05 D13 PA (NIRA) UNITIKA LTD AB EP 100382 A UPAB: 930925 Nutrient comprises an ester (I) and water. (I) may be obtd. by reaction between a carbohydrate, esp. a mono- or oligo-saccharide, and a fatty acid(s), esp. a long chain fatty acid(s). The monosaccharide is suitably glucose, fructose, xylitol or sorbitol, and the oligosaccharide may contain 2-6 sugar unit residues as a structural monomer and at least 1 glucopyranose, and it is suitably maltose, sucrose or lactose. The fatty acid is esp. oleic, linoleic or linolenic acid. The nutrient pref. contains 0.001-80 wt.% of (I), esp. 0.1-60 wt.%. The nutrient has high calorie value and it is stable, so that particles will not aggregate, thicken or create a blockage on intravenous admin. It can be infused through peripheral veins, and it creates a low osmotic pressure relative to the calories provided. A fat or carbohydrate may be added opt. with other nutrients, without aggregation occurring. It can supply 2000-5000 calories daily. 0/0
